2 Pack 110mm Toilet Lip Seal, Cassette Tank Gasket For Thetford C200 C250 C260 C400 C500 C2 C3 C4, Caravan Motorhome WC

2 Pack Contents: Includes 2 replacement sealing rings for compatible cassette toilet systems, each with a 110mm outside diameter and 20mm height. The spare pair is useful for replacing a worn lip seal during routine washroom maintenance or keeping one in the vehicle before longer caravan and motorhome trips. Model Fitment: Made for selected Thetford cassette toilet models including C200 C250 C260 C400 C500 and matching C2 C3 C4 systems where the original seal shape is the same. Check the old ring, model number and cassette layout before ordering, as toilet versions and production years can vary between waste tanks. Flexible Polymer: Made from elastic polymer material for a soft, adaptable seating surface during normal use. The ring sits between the cassette and toilet bowl area, helping maintain contact at the sealing point during daily use, cleaning and common temperature changes in caravans, motorhomes and campervans. Quick Replacement: Remove the old ring, clean the seating groove and press the new toilet lip seal evenly into position by hand. No adhesive or special tool is normally needed when the cassette type matches, but the ring should sit flat all the way round before use to avoid twisting or uneven pressure. Travel Maintenance: Suitable for cassette toilet servicing in caravans, motorhomes, campervans and boats where a tired seal may allow odour escape or liquid seepage around the waste tank area. Keeping a spare ring on board helps with touring checks, storage inspections and routine bathroom maintenance.
